An anonymous reader writes "The Polish website Moje Jabluszko ran an experiment that proves the poor reliability of the liquid contact indicators (original, in Polish) installed by Apple in the iPhone. They performed three different tests to challenge the LCIs, which they recorded as a movie. They decided to mimic regular usage of the iPhone — meaning, you go outside where it could be cold or warm, then move inside in a building where temperature might be dramatically different, but still within covered conditions. So, they placed the iPhone in its box for one hour outside at -11 C, then moved it inside at room temperature for 24 hours. They repeated the experiment 3 times, and after the third cycle they could show that the LCI located in the audio jack plug started turning red! This is a clear proof that LCIs are not reliable and could turn red while the iPhone has been used under the defined environmental requirements defined by Apple. Here, only the condensing water could have been in contact with the sensor. In other words, even moving in and out during regular winter time will make you iPhone LCI turn red!" (In the tech specs for the iPhone, Apple rates the non-operating temperature range as -20 to 45 C.)

SkydiverFL writes "For those fans of Apple's Boot Camp package, it looks like you might be waiting on the next 'end of year' to use Windows 7 on your shiny silver boxes. Back in October of this year, Apple published a rather short, but affirmative promise stating quite simply that, 'Apple will support Microsoft Windows 7 (Home Premium, Professional, and Ultimate) with Boot Camp in Mac OS X Snow Leopard before the end of the year. This support will require a software update to Boot Camp.' The support page has no updates regarding the new version. Maybe they're waiting for iSlate?"

Toe, The writes "Today Apple announced several new hardware offerings, including a new Mac mini, their (almost-literally) pint-sized desktop computer. In a bizarre twist, they are now also offering a Mac mini with Mac OS X Server bundled in, along with a two hard drives somehow stuffed into the tiny package. Undoubtedly, many in the IT community will scoff at the thought of calling such a device a 'server.' However, with the robust capabilities of Snow Leopard Server (a true, if highly GUI-fied, UNIX server), it seems likely to find a niche in small businesses and even enthusiasts' homes. The almost completely guided setup process means that people can set up relatively sophisticated services without the assistance of someone who actually knows what they are doing. What the results will be in terms of security, etc. will be... interesting to watch as they develop." El Reg has a good roundup article of the many announcements; the multi-touch Magic Mouse is right up there on the techno-lust-inspiration scale.

Etienne Steward writes "Turns out that while a few fortunes can be made with Apple, Steve Demeter made most of his money by buying Palm (of all companies) at $1.76 and selling at $12. Apparently, there aren't as many iPhone App millionaires as we would like to be believe. From the article: 'In almost a dozen interviews conducted by NEWSWEEK, Apple consultants and programmers jettison the idea that the App Store is a world of easy opportunity, or a fast track to quitting the rat race. Instead they describe an anxiety-wracked marketplace full of bewildering rules, long odds, and little sense of control over one's success or failure. "It's kind of a crapshoot," says Demeter, who spent the last two weekends partying in Las Vegas and New York. "I think we've reached a point where people are thinking I shouldn't quit my day job for this."'"

jole writes "The newest iPhone 3.1 update intentionally removed tethering functionality from all phones operating in networks that are not Apple partners. This is not limited to hacked or jailbroken phones, but also includes expensive 'officially supported' factory-unlocked phones. To make the problem worse, Apple has made it impossible to downgrade back to a working 3.0 version for iPhone 3GS phones."

bonch writes "Apple has open sourced libdispatch, also known as Grand Central Dispatch, which is technology in Snow Leopard that makes it easier for developers to take advantage of multi-core parallelism. Kernel support is not required, but performance optimizations Apple made for supporting GCD are visible in xnu. Block support in C is required and is currently available in LLVM (note that Apple has submitted their implementation of C blocks for standardization)." Update: 09/11 15:32 GMT by KD : Drew McCormack has a post up speculating on what Apple's move means to Linux and other communities (but probably not Microsoft): "...this is also very interesting for scientific developers. It may be possible to parallelize code in the not too distant future using Grand Central Dispatch, and run that code not only on Macs, but also on clusters and supercomputers."

quacking duck writes "With the release of Mac OS X 10.6 Snow Leopard, Apple has updated a support document describing how their new operating system reports capacities of hard drives and other media. It has sided with hard drive makers, who for years have advertised capacities as '1 GB = 1,000,000,000 bytes' instead of the traditional computer science definition, and in so doing has kicked the debate between marketing and computer science into high gear. Binary prefixes for binary units (e.g. GiB for 'gibibyte') have been promoted by the International Electrotechnical Commission and endorsed by IEEE and other standards organizations, but to date there's been limited acceptance (though manufacturers have wholeheartedly accepted the 'new' definitions for GB and TB). Is Apple's move the first major step in forcing computer science to adopt the more awkward binary prefixes, breaking decades of accepted (if technically inaccurate) usage of SI prefixes?"

okapi writes "Apple announced that Mac OS X v10.6 Snow Leopard will go on sale Friday, August 28 at Apple's retail stores and Apple Authorized Resellers, and that Apple's online store is now accepting pre-orders."

We've recently been following the FCC's inquiry into Apple's rejection of the Google Voice app. Apple, Google, and AT&T have all officially responded to the FCC's questions: Apple says they haven't actually rejected the app, they're just continuing to "study it," and that it may "alter the iPhone's distinctive user experience by replacing the iPhone's core mobile telephone functionality and Apple user interface with its own user interface for telephone calls, text messaging, and voicemail." The interesting bits of Google's response seem to have been redacted, but they talk a little about the approval process for the Android platform. AT&T claims it had "no role" in the app's rejection and notes that there are no contractual provisions between the two companies for the consideration of individual apps. Reader ZuchinniOne points out a report in The Consumerist analyzing some of the statements made in these filings, as well as TechCrunch's look into the veracity of their claims.

graviplana was one of several people to submit that Avatar, James Cameron's 3D Sci-Fi epic has released a trailer to whet your appetite. There's a lot of very cool visual elements in there but no indication of any actual story. Here's hoping there is one.

nate_in_ME writes "After getting a positive from the AVG virus detector while playing music on iTunes just a few minutes ago, I did a bit of research. It appears that AVG has recently pushed an update to the virus definitions that flags every iPod/iTunes related file as being infected with the 'Small.BOG' trojan. Interestingly enough, AVG does not have any information on this particular virus in their virus encyclopedia. Discussion on the Apple forum is up to 4 pages and climbing. One user there had an interesting thought: 'Maybe Palm has some shares in AVG...MUAHAAAA!!' (on page 3)."

Hugh Pickens writes "The NY Times has a story on the culture of secrecy at Apple (registration possibly required). Secrecy is not just the prevailing communications strategy; it is baked into the corporate culture that had its origin in the release of the first Macintosh. 'It really started around trying to keep the surprise aspect to product launches, which can have a lot of power,' says marketing veteran Regis McKenna who advised Apple in its early days. Today few companies are more secretive than Apple, or as punitive to those who dare violate the company's rules on keeping tight control over information. Employees have been fired for leaking news tidbits to outsiders, and the company has been known to spread disinformation about product plans to its own workers and sue bloggers who cover the company. Apple's decision to severely limit communication with the news media, shareholders, and the public is at odds with the approach taken by many other companies, and many experts agree that the secrecy that adds surprise and excitement to Apple product announcements is not serving the company well in corporate governance. Some say that recent reports that Steve Jobs may have had a liver transplant, still not confirmed by the company, now makes one of Apple's assertions from January — that Jobs was suffering only from a hormonal imbalance — seem like a deliberate untruth."

macs4all writes "Apple has finally addressed the Java vulnerability that nearly everyone else patched months ago. Available now for OS X 10.4 and 10.5, and through Apple's Software Update service, this update patches a flaw in the Java Virtual Machine that could potentially allow a malicious Java applet to execute arbitrary code on the machine. Apple had previously advised users to turn off Java temporarily in their Web browsers."

Roskolnikov writes "Apple has apparently decided that ZFS isn't really ready for prime time. We've been discussing Apple/ZFS rumors, denials, and sightings for some years now. Currently a search on Apple's site for ZFS yields only two hits, one of them probably an oversight in the ZFS-cleansing program and the other a reference to open source. Contrast this with an item from the Google cache regarding ZFS and Snow Leopard. Apple has done this kind of disappearing act in the past, but I was really hoping that this was one feature promise they would keep. I certainly hope this isn't the first foot in the grave for ZFS on OS X."

SkiifGeek writes "Both Microsoft and Apple have released major security updates in the last 24 hours. Microsoft's single update (MS09-017) addresses fourteen distinct vulnerabilities across all supported versions of PowerPoint, but it isn't the number of patched vulnerabilities that is causing trouble. Instead, the decision to release the patch for Windows versions while OS X and Works versions remain vulnerable to the same remote code execution risks (including one that is currently being exploited) hasn't gone down well with some people. Microsoft have given various reasons why this is the case, but this mega-update-in-a-patch is still interesting for other reasons. Meanwhile, Apple has updated OS X 10.5 to 10.5.7 as part of the 2009-002 Security Update, as well as a cumulative update for Safari 3 and the Public Beta for 4. As well as addressing numerous significant security risks, the 10.5.7 update provides a number of stability and capability enhancements and incorporates the Safari 3 update patch. Probably the most surprising element of the Apple update is the overall size of it; 442MB for the point update, and 729MB for the ComboUpdate."

Afforess writes "A recent closer look at the oft-skimmed EULA agreement for iTunes has an interesting paragraph in it, Gizmodo reports. 'You also agree that you will not use these products for any purposes prohibited by United States law, including, without limitation, the development, design, manufacture or production of missiles, or nuclear, chemical or biological weapons.' Although humorous, some readers suggested that this may be a defense measure to previously discussed price changes in the iTunes music store."

An anonymous reader writes "Apple has posted a counter of App Store downloads as they approach one billion downloads. The lucky billionth downloader gets to walk away with a stash consisting of a MacBook Pro, 32GB iPod Touch, Time Capsule and $10,000 iTunes gift certificate. The App Store now has over 30,000 applications."

bowman9991 writes "Bryan Fuller, creator of the TV show Pushing Daisies and a former Star Trek writer and producer, is geared up to make it happen. The new Star Trek TV show would be based on "old style" Star Trek, rather than the more recent incarnations and variations: Deep Space Nine, Voyager, Enterprise and Star Trek: The Next Generation. There hasn't been a Star Trek TV series since Enterprise was canceled after four seasons in 2005. Fuller wrote twenty one Star Trek episodes over four years, two in Deep Space Nine's final season, and the rest for Voyager. He also produced Voyager's last season. If J.J. Abrams' reboot is successful (and the latest trailer suggests it will be!) perhaps we'll see him involved with a new Star Trek TV show with the style and impact of Fringe or Lost. The new Star Trek movie featuring a young Kirk and Spock is in cinemas May 2009." Besides his work on many episodes of Trek, Fuller's work includes Dead Like Me and some of the best of Heroes. (He's one of the names I actively seek in the writing slot.) Between him and JJ Abrams, the era of Rick Berman looks to finally be at an end. Cross your fingers.

mikesd81 writes "ZDNet Australia writes that NSW state corporation RailCorp has threatened a Sydney software developer with legal action if he fails to withdraw a train timetable application that is currently the second-most-popular application in its category in Apple's App Store. Alvin Singh created Transit Sydney after he began teaching himself how to program in Cocoa Mobile. Within days of its Feb 18 release, Singh received a cease and desist notice from Rail Corporation NSW, the government body that administers Sydney's CityRail network. The email states: 'I advise that copyright in all CityRail timetables is owned by RailCorp. ... Any use of these timetables in a manner which breaches copyright by a third party can only occur through the grant of a suitable licence by RailCorp.'" "As a government body, RailCorp information is protected by Crown copyright, a contentious provision in copyright law that has recently been used to block attempts to access information on the location of Victoria's bushfires and even seemingly innocuous information as the locations of public toilets. 'RailCorp's primary concern here is that our customers receive accurate, up-to-date timetable information,' RailCorp spokesperson Paul Rea explained. 'This includes details of service interruptions, special event services, track work and other changes. ... At this stage, it is not possible for RailCorp to grant third-party developers access to our internal passenger information systems. As such, any third-party CityRail timetable application would contain inaccuracies and have the potential to mislead our customers.'"

An anonymous reader writes "After being down for a couple of hours, the Apple store reopened this morning. All of the speculation has turned out to be a reality with Apple dishing out many new products and among them are; iMac 20", three iMac 24" models, two Mac Mini models, and two Mac Pro models — with one including an ATI Radeon HD 4570 graphics card. Also as rumored, there was the new Airport Extreme, and Time Capsule in 1TB. The Mac Pro is the granddaddy of them all. The lower-end Quad Core system includes a 2.66Ghz Quad-Core Intel Xeon processor, 3GB of memory, 640GB hard drive, 18x double-layer Superdrive, and a NVIDIA Geforce GT 120 with 512MB of memory priced at $2,499. Finally, we have the 8-core system which includes two 2.26Ghz Quad-Core Intel Xeon processors, 6GB of memory, 640GB hard drive, the 18x double-layer Superdrive, and of course the NVIDIA Geforce GT 120 with 512MB of memory priced at $3,299."

CNETNate writes "Apple has released the beta version of Safari 4 for Mac and PC, with claims that its Nitro rendering engine is '30 times faster than IE7,' and three times faster than Firefox 3. Other new features include 'Top Sites,' which shows users the most frequently visited Web pages, 'Full History Search' for searching through not only the URLs and titles of visited pages, but also the complete text within the page itself — something Opera has been doing for a while."

Cory Foy writes "When my wife got a Touch several months back, the first thing I wanted to do was build some applications for it. Who wouldn't want to play with a device that has accelerometers, position sensors and multi-touch gestures? But being new to the Mac world, I needed something to help guide me along. Beginning iPhone Development aims to be that guide. But does it live up to the challenge of teaching a newbie Mac and iPhone developer?" Read below for the rest of Cory's review. Beginning iPhone Development: Exploring the iPhone SDK author Dave Mark, Jeff LaMarche pages 536 publisher Apress rating Five $1000 Rubies reviewer Cory Foy ISBN 978-1-4302-1626-1 summary A great introduction to the iPhone SDK and getting into iPhone Development The first thing you'll need to do is head over to the Apple Developers Site and register for an account. You can then download the iPhone API. Note that while the API download and simulator are free — deploying to a real iPhone or iTouch is not, even if it is your own. To do that you have to apply to the iPhone Developer Program which is $99. For the book, you'll be fine with just the simulator with the exception of any accelerometer application, since the simulator doesn't have that feature.

With that out of the way, I was quite impressed with the book. Although I've done quite a bit of development in the past, I haven't worked with Objective-C before, and was a little concerned if I would be in over my head. If you are in that position, don't fear — the authors do a great job of walking you through, and you'll find yourself working with it in no time.

The first chapters introduce you to the basics of the iPhone and development, starting with the canonical "Hello, World" application. The book walks you through how to get and install Xcode and the iPhone API. It then introduces you to Interface Builder, the partner-in-crime to Xcode. Even in the first chapter, the authors show their attention to detail, explaining common issues you might run into (like trying to Build and Run while your iPhone or iTouch is plugged in to your Mac).

Chapter 3 introduces the Model-View-Controller paradigm, a pattern that is probably one of the most misunderstood patterns in UI development. They give you enough information to be familiar with the terms you'll be using, and they very much mean it when they tell you not to worry if you aren't understanding something — they always loop back around to make sure you understand it.

Chapter 4 was a long chapter for me, but introduces some important concepts around user interaction and controls. By the end, you have an interface which has a variety of controls which interact with each other. As with the other chapters, the authors introduce tips and tricks to make things easier (for example, Option->Cmd->Up Arrow to switch from the header to implementation file in Xcode).

Chapter 5 covers autorotation and basic animations, including linking in the Core Graphics Framework. I especially like how the authors gave three different ways of making your app auto-rotation aware, describing the benefits and drawbacks of each. Chapter 6 follows this up by introducing multi-view interfaces, something very necessary as you get into more complex iPhone development.

Chapters 7-9 describe various methods to presenting information to users, including toolbars, table views, hierarchical navigation and hierarchical lists. However, it isn't all drag-n-drop, the authors get into some good (and sometimes deep) conversations about what you are doing. For example, in Chapter 8, they talk about issues with NSDictionary and how to create deep mutable copies.

Chapters 10-13 are the last of the "fundamentals" — application settings, basic data management, custom drawing using Quartz and Open GL, and taking inputs (including gestures and multi-touch). As someone who spends most of his time as far away from graphics libraries as possible, I was quite impressed with the basics that were introduced and what someone like me could get up and running.

Finally we get into the fun. Chapter 14 introduces Core Location, allowing to figure out where in the world you are. The book goes through a discussion about the various ways to get location information, and drawbacks of each. (Helpful tip: no matter which method, if you are polling every second, you'll drain the battery pretty quickly). For the simulator-only users, this is when things start to become tricky. Chapter 14 does work, though you aren't prompted for access to Core Location.

Chapter 15, however, is useless without an actual phone, even though it's perhaps the most fun. In this chapter, the book goes through the accelerometer and all the interesting things you can do with it. There's even a small discussion on the physics (but just enough!). Both apps you create (Shake and Break and the Marble game) are quite fun for someone just starting out with all of this. It's a shame Apple couldn't figure out a way yet to include the accelerometer in the simulator.

Chapter 16 covers using the iPhone camera and Photo Library. It's short, but it shows the power of the simple interfaces Apple provides. In just 9 pages you'll be capturing images right from the iPhone.

The final two chapters I thought were quite fitting — Localization and Follow-Ups. In the localization chapter, the book covers extracting strings out to resource files and using locale to read them in. Having a day job which ships our software in 12 different languages, I know first-hand how difficult localization can be to get right, so I was glad to see this chapter. The final chapter is just a wrap-up of resources you can reach out to for help and information.

All in all I was very surprised and pleased with the book. I've had the fortune of reading many technical books, and few do a great job of walking someone through the basics without making them feel like a dolt. It felt like every time I was stuck or unsure there was a tip, hint or paragraph which explained what was going on.

The main drawback to me is the fee to deploy apps to your own phone. This wasn't something I ran into doing either J2ME or Windows Mobile apps in the past, and it is a shame that to even work on your own phone you have to pay a fee. However, since the fee does give you the ability to submit apps to the App Store, then I guess it's a consolation. I'd rather Apple lock deployments to one iPhone (or iTouch) for the truly casual people who just want to do interesting things on their own phone.

In summary, I give this book five $1000 Rubys for making a clean, concise, easy-to-read and follow introduction to iPhone development. Great job guys!

An anonymous reader writes with this excerpt from Network World: "A number of sites are reporting that Apple's CEO Steve Jobs is taking a leave of absence till June at least. Speculation over Jobs' possibly failing health has run rampant in the past few weeks. Prior to the recent MacWorld show, Jobs said he had a hormone deficiency that had caused him to dramatically lose weight. In a memo today Jobs told workers his health issues are more complex than he thought." Reader Bastian227 adds a link to this letter from Steve Jobs on Apple's website, which also says that Tim Cook will be responsible for daily operations, though Jobs will remain involved with major strategic decisions.

ptorrone writes "Make: television debuted online and on public television (broadcast / cable tv). The series encourages everyone to invent, reinvent, recycle, upcycle, and act up. Based on the popular Make magazine, each half-hour episode hopes to inspire viewers to think, create, and, well, make. Each episode can be viewed or downloaded DRM-free, in HD on makezine.tv — the show is also available on Vimeo, YouTube, blip.tv and iTunes."

i4u writes "Rumors about Steve Jobs' health have been flying high again after Apple announced that he will not be holding the keynote at the Macworld 2009. Today Steve Jobs issued a letter with a rather personal update on why he was losing weight in 2008. The reason for losing weight in 2008 is a hormone imbalance that has been reducing proteins. The remedy for this nutritional problem is relatively simple and straightforward according to Jobs. Steve and his doctors predict that he will have normal weight again by Spring. So stop the rumors and enjoy Macworld 2009."

Newscloud writes "As PC Mag reported last week, Apple OS X 10.5.6 can break some MacBook Pros leaving some users (like me) with a dead backlit black screen after the Apple logo appears. While I initially thought I had a hardware failure, it turns out that there is a fix as long as you have an external display, keyboard and mouse. The problem only appears on the second restart, so if you sleep your MacBook a lot as I do, you might not realize the problem is related to the OS update you did the week before. The problem was related to older, incompatible firmware that Software Update wasn't flagging before the upgrade. This definitely gives weight to the argument for waiting a bit to run software upgrades."

Many readers including thermopile wrote in about Apple withdrawing from Macworld Expo after this year. The other bad news for Apple fans is that Steve Jobs won't be delivering the keynote in 3 weeks — we may have seen his last "one more thing." Apple VP Phil Schiller will be doing the honors. He's "an Apple executive notably lacking in Jobs's showmanship and star power," according to the Fortune blogger. Apple's press release states that "trade shows have become a very minor part of how Apple reaches its customers." While this may be true, the keynote addresses have been a critical venue for major new product announcements. Apple's stock is taking a 6% hit in after-hours trading, possibly on concerns about Jobs's health. Reader Harry has gathered together YouTube clips from most of the Macworld keynotes Jobs given since 1997.

Barence writes "After years of boasting about the Mac's near invincibility, Apple is now advising its customers to install security software on their computers. Apple — which has continually played on Windows' vulnerability to viruses in its advertising campaigns — issued the advice in a low-key message on its support forums. 'Apple encourages the widespread use of multiple antivirus utilities so that virus programmers have more than one application to circumvent, thus making the whole virus writing process more difficult.' It goes on to recommend a handful of products." Reader wild_berry points out the BBC's story on the unexpected recommendation.

A woman calling herself Susan042764 posted a question on the Apple support forums asking if a "technical glitch" could be responsible for nude photos of her husband she found attached to an email. She wrote,"Please help! I took my husband's iPhone and found a raunchy picture of him attached to an email to a woman in his sent email file. When I approached him about this, he admitted that he took the picture, but says that he never sent it to anyone. He claims that he went to the Genius Bar at the local Apple store and they told him it is an iPhone glitch — that photos sometimes automatically attach themselves to an email address and appear in the sent folder, even though no email was ever sent. Has anyone ever heard of this happening?" Assuming this is true, it has to be one of the lamest excuses ever.

CWmike writes "Apple customers, unhappy that the company dropped FireWire from its new MacBook (not the Pro), are venting their frustrations on the company's support forum in hundreds of messages. Within minutes of Apple CEO Steve Jobs wrapping up a launch event in Cupertino, Calif., users started several threads to vent over the omission. 'Apple really screwed up with no FireWire port,' said Russ Tolman, who inaugurated a thread that by Thursday has collected more than 300 messages and been viewed over 8,000 times. 'No MacBook with [FireWire] — no new MacBook for me,' added Simon Meyer in a message posted yesterday. Several mentioned that FireWire's disappearance means that the new MacBooks could not be connected to other Macs using Target Disk Mode, and one noted that iMovie will have no way to connect to new MacBooks. Others pointed out that the previous-generation MacBook, which Apple is still selling at a reduced price of $999, includes a FireWire port. Apple introduced FireWire into its product lines in 1999 and championed the standard."

Paige Philuer writes "Macworld has a hands-on article examining the new MacBook and MacBook Pro — not a quickie look from Tuesday's event, but a lengthy, in-depth look with laptops they actually have in their offices. Some interesting observations: No FireWire on the MacBook; the TrackPad doesn't feel like you're running your finger across a pane of glass, though that's what it is; and switching between graphics cards in the MacBook Pro requires you to log out." Reader Bourbon contributes three links at CNET related to the new models, too: a positive written review (giving a score of 8/10 to the new MacBook), a video review, and a behind-the-scenes look at how the new models are machined.

theodp writes "If you're a PC, you may be unfamiliar with The Dock, the bar of icons that sits at the bottom or side of a Mac and provides easy access to Apple applications. But don't count on it becoming a standard on the PC. On Tuesday, the USPTO awarded Apple — and inventor Steve Jobs — a patent for their User Interface for Providing Consolidation and Access, aka 'The Dock,' after a rather lengthy nine-year wait."

ds writes "Apple, this morning, announced they are dropping the iPhone Developer NDA in respect to released software. Previously, iPhone developers were legally bound even after their software had been released." Another reader adds, "Early release software is still covered, but this should bring about increased developer interaction, as well as a slew of iPhone dev books." The complete message about the NDA change can be seen for now at Apple's iPhone Developer site, and is reproduced below. "We have decided to drop the non-disclosure agreement (NDA) for released iPhone software. We put the NDA in place because the iPhone OS includes many Apple inventions and innovations that we would like to protect, so that others don't steal our work. It has happened before. While we have filed for hundreds of patents on iPhone technology, the NDA added yet another level of protection. We put it in place as one more way to help protect the iPhone from being ripped off by others. However, the NDA has created too much of a burden on developers, authors and others interested in helping further the iPhone's success, so we are dropping it for released software. Developers will receive a new agreement without an NDA covering released software within a week or so. Please note that unreleased software and features will remain under NDA until they are released. Thanks to everyone who provided us constructive feedback on this matter."

rickthewizkid writes "Recent updates to the iTunes software allow blind users to access the program without assistance. From the article: 'The new software — which transforms the written information on an iTunes-linked computer screen into speech or Braille — stemmed from an agreement between Apple, the Cupertino, Calif.-based computer company, the National Federation of the Blind and Massachusetts Attorney General Martha Coakley.'" It's not just the actual iTunes app, though; the article notes that this update makes iTunes U useable as well.

jesuscash writes "It seems early adopters of the new iPod Touch are out of luck when they bring it home and attempt to connect it to their WPA/WPA2 secured network. Reading this Apple forum thread shows that many tests with different configurations show a no-go on WPA. Some of the last entries give the best clue, revealing a 'received deauthentication' error in their router logs. Apple has yet to respond."

CWmike writes "Apple 's latest version of iTunes crashes Windows Vista when an iPod or iPhone is connected to the PC, scores of users have reported on Apple's support forum. Plug in and Vista crashes and shows the 'blue screen of death.' The errors began showing up immediately after updating iTunes to Version 8.0, which Apple released Tuesday as part of its iPod refresh. 'I just installed iTunes 8 over my iTunes 7 on Vista [and] now whenever I plug in my iPod, I get a blue screen death. Three times so far. Even if it is plugged in on boot, I get a blue screen," said a user identified as 'sambeckett' on the support forum about 90 minutes after Apple CEO Steve Jobs wrapped up the iPod launch."

CWmike writes "Apple's iPhone 3G was just a couple of days old when reports began trickling onto the company's support forum from dissatisfied customers complaining about poor reception. Although no one outside of Apple and AT&T — and maybe a chipmaker or two — really knows, that has not kept others from speculating, or in a few cases, making claims based on unnamed sources. What's going on? We may not have all the answers, but we do have questions. Gregg Keizer put together everything we know in a FAQ on the griping about iPhone 3G reception."

Alexander Burke writes "Apple has just released Security Update 2008-005, which patches BIND against the Kaminsky DNS poisoning issue. 'This update addresses the issue by implementing source port randomization to improve resilience against cache poisoning attacks. For Mac OS X v10.4.11 systems, BIND is updated to version 9.3.5-P1. For Mac OS X v10.5.4 systems, BIND is updated to version 9.4.2-P1.' It also closes the script-based local privilege escalation vulnerabilities, the most common examples of which were ARDAgent and SecurityAgent, and addresses other less-publicized security issues as well." A few days back we noted Apple's tardiness in fixing their corner of this Net-wide issue.

snydeq writes "InfoWorld's Tom Yager takes a closer look at Apple's iPhone SDK confidentiality agreement, which restricts developers from discussing the SDK or exchanging ideas with others, thereby leaving no room for forums, newsgroups, open source projects, tutorials, magazine articles, users' groups, or books. But because anyone is free to obtain the iPhone SDK by signing up for it, Apple is essentially branding publicly available information as confidential. This 'puzzling contradiction' is the 'antithesis of the developer-friendly Apple Developer Connection' on which the iPhone SDK program is based, Yager contends. 'You'll see arguments from armchair legal analysts that the iPhone developer Agreements won't stand up in court — but those analysts certainly won't stand up in court on your behalf.' Anyone planning to launch an iPhone forum or open source project should have 'a lawyer draft your request for exemption, and make sure that the Apple staffer granting it personally commits to status as authorized to approve exceptions to the iPhone Registered Developer and iPhone SDK Agreements,' Yager warns."

L. Miriam writes "Apple launched the iTunes App store for the iPhone and iPod Touch today, following the earlier launch of iTunes 7.7. There are over 500 applications available for download, with prices ranging from free to around $35. Both MySpace and Facebook apps are there, as well as a mix of games, utilities and ebooks. You can download applications now, but you can't do anything with them until the iPhone/iPod 2.0 firmware is released. The App Store can't be accessed directly through iTunes, but Mobile Computer explains how to get to it, and has a few screenshots, too."

An anonymous reader writes "The iPhone 3G and Android devices are coming this year, opening the mobile world for rich applications, while sites like Fire Eagle and byNotes are ready to move your blogging habits into the geospatial world. Are we going to watch the next boom when those devices and geospatially enabled sites get combined? Sure, the posibilities this would open are endless, but are users going to embrace these services?" I don't see how it can't change the world ... it has 'Micro' and 'Blog' in the name, and I'll always know where I was when I twittered to tell everyone I was in the john.

jyosim writes "A site called Textbook Torrents is among the many sites popping up offering free downloads of expensive textbooks using BitTorrent or other peer-to-peer networks. With the average cost of textbooks going up every year, and with some books costing more than $100, some experts say that piracy will only increase." Having just completed graduate school, I can attest that quite a few books are in that more-than-$100 range, and that they're heavy besides. But the big-name textbook publishers are much less interested than I am in open textbooks, even if MIT has demonstrated that open courseware is feasible, and Stanford and other schools have put quite a bit of material on iTunes.
